In the research and development of large language models (LLMs), evaluation is essential for accurately understanding their capabilities and limitations. With the recent advancements in LLMs, their evaluation benchmarks and methods also require updates. This presentation will organize evaluation challenges and the latest trends from multifaceted perspectives, including knowledge, reasoning, multilingual support, increasing difficulty, and LLM agents. Furthermore, as an evaluation practice in Japanese LLM development, we will introduce the evaluation frameworks swallow-evaluation and swallow-evaluation-instruct developed within the Swallow Project.
